dc.description.abstract Ultrasound-assisted extraction was used to determin e the optimum processing conditions and to achieve the maximum extraction yi eld and viscosity of the gum extracted from quince seed. Using Response Surface Methodology (RSM) to design the experiments and adopting the Central Composite Rota table Design (CCRD), the effect of extraction temperature (25-55°C), time (3-10 minute s), and pH (6-8) were evaluated on efficiency of gum extraction yield (%) and viscosit ies (mPas) . The Chemical composition of the extracted gum was determined using AOAC stan dard methods. Apparent viscosity of the gum was measured by rotational viscometer. U sing multiple linear regression analysis, a second-order polynomial model was devel oped for each response. The quince seed gum showed pseudoplastic behavior. Optimum ope rating conditions based on the highest yield and viscosity was predicted by RSM as an extraction temperature of 38.03 ◦ C, pH of 6.35 and the extraction (ultra-sonication) time of 7.68 minutes. At this optimum point, extraction yield and viscosity were 14.09% and 52.4 mPas, respectively.
